It's because of this sort of thing that I've long been on the Secret Service's, FBI's, and CIA's real shitlist. Not the one about threats to the nation... the one of jerks who call us and try to tell us how to do our job. I believe they do great work, I hope they understand; I just have a thing about the way in our sophistication we so often overlook the should be obvious (think the Apollo 1 tragedy, and how NASA got away with pressurizing vessels with 100% oxygen for nearly a decade).
